BOX-COVERING MACHINE.

Application fiI'edJuly 12, 1922. Serial No. 57 M115.

T0 (ZZZ whom it may concern.

Be it known that I, FRANK E. HATCH, a citizenzof the Uni-ted t-States, and a'resident of Rutherford,inthe county of Bergen and State of New Jersey, have inventedcertain new and useful Improvement-s in Box-Govering Machines, of which the following .is a specification.

This invention relates to box coveringmachin'ery and particularly to machinery for covering the sides of paper boxes with gummed paper strip fromrolls ofthe same.

The main obj ectof the invention isto provide improved 'means for Wrapping the gummed paper strip around the sides of the box body and properly securing it to all parts thereof. Another object is to-provide improved means-for turning over and securing one of the side edges of-the gummed paper strip and attaching it to the-bottom edgesof the box, and awthird object is to provide improved means for turning over and attaching the other side edge ofssaid strip to the inside of the top edges of the box. Still another-object is to-provideimproved'mean-s to form neat folds of said strip edges at the bottom corners oft'hebox. Other features consist .in improvements in certain mechanism ofthe type discloseld'in my co -pending. application, Serial No. 396,- 823, filed.Jul-y '16, 1920. V

"The means'xvhich I=preferr2lbly employto accomplish the foregoing-objects are illustrated in the drawings accompanying and formingpart of this specification, and "in Which Figure 1 is a side elevation'of my improved box-covering mechanism as appliedat the delivery end of gumined paper strip.

means {for supplying "Fig. ll-is a perspective view of a device to act in turning over the. strip edge at the'bottom edges of-the box.

Like characters of referencev refer to like parts in all the figures ofthe drawings.

My improvements are used. in connection with mechanism 2for supplying gummed paper strip, and'mechanismffor cutting oil sections of the paper strip of the proper length to wrap around the sides of a box, and as their a'pplicati-on'is Well understood in-the'a-rt, they are. omittedin the drawings forthe sake of clearness. Thewrapping of thepaperystrip. around a box can b e effected hyturningth box or turning the Wrapping mechanism. and allowvi-ngthe box'to remain stationary. In the drawings, former method isemployed, andthe box2 is preferably mounted on aform 3, securedto a shaft 4:, rotatable ina bearing 5 on themachine frame; There is a frame 6, having a pair of arms such as 7, suitably braced together, andhingedat-the fOIXValTllPEITl' Of the machine frame 8, onxavhich also are mounted the strip gumming'anfd guiding means (not shown). l\/I-o-unted"insuitableibearings'9 in said ,arms,'is apivot-shalft 10, and pivoted on said shaft isa "frame designatedby 11 and; located laterally ongthe shaft by, collars 12. .A guidel3-secin edto the-frameS and provided'with a slot ll-through-vvhich one of the arms 7 its arms 7, in lateral alinement.

Suitablemechanism, Well known in theQart andtherefore omittedherein ,for the sake of clearness, revolves the shaft 4: and box passes, holdsth -jfran e fi and form3', one revolution at a time, after which they. come to rest. Just before; the shaft and form come to rest, the cutting-off device severs the paper strip, so that'the end is Wrapped onto the box When it completes a revolution.

'.The frame 11 has side plates 15, spaced by rods 16, held by nuts 17, and has a shaft 18 passingthrough it forward ofand below the-pivot shaft 10, and positioned in the frame by collars 1.9. On the shaft 18 is a roll 21, preferably 1 rubber-covered, and. p0sitioncd by=collars '22 tortur'n on said shaft. There is also a second shaft 23 in the frame Ill) and adapted to 11, positioned by collars 24,

Secured to the turn in the side-plates 15.

shaft 23 are two members 25, 26, which act shaft 23 passes, and a set screw in the lug 28 which secures the lug and plate to the said shaft 23. Also mounted on the shaft 23 is an arm 32 having a hub 33, by means of which it is journaled on an extension or sleeve 34 of the lug 28, and it is held in position laterally by the collar 35. The arm 32 has a hub at its outer end in which is journaled a rod 36 secured to the member 37. A spring 50 connects to a flexible member 501 secured to the hub 33 and causes the arm 32 to press the member 37 downward. The member 37 is of rightangled cross-section and has two flat bearing surfaces 38 and 39, each of which is curved at the front toward the supply portion of the machine, so as to readily pass over the sides and bottom of the box. The curved part designated by 40 and which precedes the surface 38, folds down and attaches all the portions of the edge of the paper strip which have not been acted upon by another member hereinafter to be described.

The member 25 has a plate 41, curved at the forward part, and a lug 42 by means of which it is secured to the shaft 23 by a screw 43. On the lug 42 is a bifurcated oscillating member 44, having a roll 45 at the top, and a member 46 secured to one side. The member 46 has curved lips 47, a groove 49, and a curved or warped surface 48 adjacent to said groove. A spring 51 around the pivot screw normally presses the member 44 and roll 45 towards a relatively stationary cam member 52, and hung on the shaft 10 above the roll 45 is a movable by-pass member 53 for a purpose hereinafter to be explained.

On the forward part of the plate 27 is a lug 55, and a link 56 is hinged thereto, and at its other end also to one arm of an adjustable bell-crank 57 ournaled on the shaft 10. A wiper 58 is secured to the outer part of the other and longer arm 59 of the bellcrank 57 and is adapted to be moved to-and fro or oscillated by means of the link 56 which is actuated by the movement of the plate 27 following the rotation of the box. The wiper 58 has a beveled edge 58 and also has a stem 60 by which it is held in a suitable bearing 61 in the arm 59, and has a spring 62, so that it shall be slightly yielding when brought into action.

Journaled on the shaft 23 is an arm 65, having a stud 66 at the end thereof. A triangular member 67 is journaled at the end of said stud so as to freely turn thereon, and a coil spring 68 presses the triangular member 67 inwards towards the box edge so that its flange 69 comes against said edge. An arm 70 is also journaled on the shaft 23 and is connected to the arm 60 through the medium of a spiral spring 71 surroui'iding the shaft and secured respectively to the hub of the arm 65 and to a pin 72 in the arm 70. Journaled to a stud 75 in the end of the arm 70 is a member 76 which is adapted to slide over the outer portions of the top edges of the box and prevent the said edges from being pushed outward by the member 67.

The operation of my improved box covering machine is as follows:

When the arms 7 and frame 11 are raised, a box is placed in position on the form 3, and the end of the paper strip 5, which has just passed through the usual gumming means and around the guide rolls m, 7), is pulled along and attached to the side of the box that is uppermost.

The frame 11 and arms 7 are now let down so that the roll 21, and members 25, 26, rest on the end of the paper strip on the box. The box 2, form 3, and shaft 4 are now allowed to make a revolution, and the paper strip is pressed onto the side of the box by means of the roll 21, together with the double member 25, 26, and the edge-turning mechanisms are positioned thereon, principally by the double wiper 25, 26.

The edge of the strip at the top of the box is turned over by the member 46, of which the curved lips 47 act first, then the curved or warped surface 48 turns the paper, and then the groove 49 acts thereon. These various portions turn over the strip edge into a U-form which is pressed onto the top edges of the box. The flat surfaces 64 of the triangular member 67 press the lower part of the U against the inside of the top edges of the box, and the points 73 pass into and press home the insides of the corners as they successivelv come to said member. The member 76 presses down on the outer side of the top edges and prevents them from being sprung outward by the corner presser.

The member 46 is oscillated outward at each corner of the box and moved back into folding position again on passing the corner, by the riding of the roll 45 on the cam 52. held thereon by the pressure of the spring 51, after which it rides. in the reverse direction over the left hand face of the bypass member 53, and on reaching the edge ion '80 thereof, 'moves "suddenly back toward the cam. The last =movement causes 'the member e6 to be brought back to its folding position and very close to the corner of the box. These operations occur at each corner.

At the bottom edges of the box 'the wiper 58 is caused to move downwardjust before the corner of the box passes. The downw'ard oscillation of this member brings the beveled edge -58"against the paper strip edge and folds down a portion thereof before the corner and causes it to adhere by its egum'med surface to the bottom edgesof the box. The beveled edge '58 starts a beveled fold next'to the corner. The member 58 is immediately raised and the-corner passes by. The member 37 slides continuously over thestrip edge and folcsdown and attaches the portions not touched by the wiper 58, and also passes over those parts folded-bythe member 58, and finishes the beveled fold atthe 'corners-tdthe form illustrated in Figs. 3 and '9. The fini'shed box is removed by pulling back the member 67 and raising the arms 7 and frame 1-1.

In order to maintain the box closely against the box form at all times "during the wrapping operation, I have provided a member to press on the bottom of the box at a point a little distance from the edge of'the bottom, Preferal'ily said-member is a rollsuch as 85,- in a bracketSG-secured to the adjacent side plate of the frame 11. p

The two paper-strjip-e-dge-turning mechanisms are adapted for nse'o'n a. greatnumber of ditlerent'sizes of boxes without any readjustment except for width. This is due to the 'fact that the said mechanisms are always correctly spaced with relation to the box edges and corners, by the frame -11, roll 21, and wipers 25, 26.

It is evident that the mere mechanismfor giving the movements to the various parts of'the above'described mechanism can "be varied and any suitable forms ofiparts may be employed without departing from the spirit and principle of my invention and I donot therefore confine myself to the details of construction here" shown.
